Using my Goodson 1.8″ – 2.6″ valve spring height gauge, we set final spring installed height at 2.150″. The original valve guides protruded a tad too high for adequate retainer-to-guide-seal clearance. Using a 1/2″ guide cutter and an 11/32″ pilot, I cut the guides down by 0.147″. During intake manifold and gasket test fitting, I [...]
